Adjusting bit protrusion (Fig. 2 & 3)
To adjust the bit protrusion, loosen the lever and move the
tool base up or down as desired by pressing and turning
the adjusting roller. After adjusting, tighten the lever firmly
to secure the tool base.
Switch action (Fig. 4)
CAUTION:
Before plugging in the tool, always be sure that the tool is
switched off.
To start the tool, move the switch lever to the "I" (ON)
position. To stop the tool, move the switch lever to the "0"
(OFF) position.
The tool equipped with electronic function is easy to
operate because of the following features.
Operation
• Set the tool base on the workpiece to be cut without the
bit making any contact. Then turn the tool on and wait
until the bit attains full speed. Move the tool forward over
the workpiece surface, keeping the tool base flush and
advancing smoothly until the cutting is complete.
• When doing edge cutting, the workpiece surface should
be on the left side of the bit in the feed direction. (Fig. 5)
NOTE:
• Moving the tool forward too fast may cause a poor quality
of cut, or damage to the bit or motor. Moving the tool
forward too slowly may burn and mar the cut. The proper
feed rate will depend on the bit size, the kind of workpiece
and depth of cut. Before beginning the cut on the actual
workpiece, it is advisable to make a sample cut on a piece
of scrap lumber. This will show exactly how the cut will
look as well as enable you to check dimensions.
• When using the trimmer shoe, the straight guide or the
trimmer guide, be sure to keep it on the right side in the
feed direction. This will help to keep it flush with the side
of the workpiece. (Fig. 6)
CAUTION:
Since excessive cutting may cause overload of the motor
or difficulty in controlling the tool, the depth of cut should
not be more than 3 mm at a pass when cutting grooves.
When you wish to cut grooves more than 3 mm deep, make
several passes with progressively deeper bit settings
Straight guide
The straight guide is effectively used for straight cuts when
chamfering or grooving. (Fig. 7)
Attach the guide plate to the straight guide with the bolt
and the wing nut. (Fig. 8)
Attach the straight guide with the clamp screw (A). Loosen
the wing nut on the straight guide and adjust the distance
between the bit and the straight guide. At the desired
distance, tighten the wing nut securely. (Fig. 9)
When cutting, move the tool with the straight guide flush

with the side of the workpiece.
If the distance (A) between the side of the workpiece and
the cutting position is too wide for the straight guide, or if
the side of the workpiece is not straight, the straight guide
cannot be used. In this case, firmly clamp a straight board
to the workpiece and use it as a guide against the trimmer
base. Feed the tool in the direction of the arrow. (Fig. 10)
Circular work
• Circular work may be accomplished if you assemble the
straight guide and guide plate as shown in Fig. 11 or 12.
Fig. 11 for cutting circles between 70 mm and 121 mm
in radius.
Fig. 12 for cutting circles between 121 mm and 221 mm
in radius.
NOTE:
Circles between 172 mm and 186 mm in radius cannot be
cut using this guide.
• Min. and max. radius of circles to be cut (distance
between the centre of circle and the centre of bit) are as
follows:
Min.: 70 mm
Max.: 221 mm
Align the centre hole in the straight guide with the centre of
the circle to be cut. Drive a nail less than 6 mm in diameter
into the centre hole to secure the straight guide. Pivot the
tool around the nail in clockwise direction. (Fig. 13)
Trimmer guide
Trimming, curved cuts in veneers for furniture and the
like can be done easily with the trimmer guide. The guide
roller rides the curve and assures a fine cut. (Fig. 14)
Install the trimmer guide on the tool base with the clamp
screw (A). Loosen the clamp screw (B) and adjust the
distance between the bit and the trimmer guide by turning
the adjusting screw (1 mm per turn). At the desired
distance, tighten the clamp screw (B) to secure the
trimmer guide in place. (Fig. 15)
When cutting, move the tool with the guide roller riding the
side of the workpiece. (Fig. 16)
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and unplugged
before carrying out any work on the tool.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only
identical carbon brushes. (Fig. 20)
Use a screwdriver to remove the brush holder caps. Take
